Towards half-past one, the colonists embarked in the boat to visit the wreck. It was to be regretted that the brig's two boats had not been saved; but one, as has been said, had gone to pieces at the mouth of the Mercy, and was absolutely useless; the other had disappeared when the brig went down, and had not again been seen, having doubtless been crushed.

The hull of the _Speedy_ was just beginning to issue from the water.

The brig was lying right over on her side, for her masts being broken, pressed down by the weight of the ballast displaced by the shock, the keel was visible along her whole length. She had been regularly turned over by the inexplicable but frightful submarine action, which had been at the same time manifested by an enormous water-spout.

The settlers rowed round the hull, and, in proportion as the tide went down, they could ascertain, if not the cause which had occasioned the catastrophe, at least the effect produced.

Towards the bows, on both sides of the keel, seven or eight feet from the beginning of the stem, the sides of the brig were frightfully torn.

Over a length of at least twenty feet there opened two large leaks, which it would be impossible to stop up. Not only had the copper sheathing and the planks disappeared, reduced, no doubt, to powder, but also the ribs, the iron bolts, and tree-nails which united them. From the entire length of the hull to the stern the false keel had been separated with unaccountable violence, and the keel itself, torn from the carline in several places, was split in all its length.

"I've a notion!" exclaimed Pencroft, "that this vessel will be difficult to get afloat again."

"It will be impossible," said Ayrton.

"At any rate," observed Gideon Spilett to the sailor, "the explosion, if there has been one, has produced singular effects! It has split the lower part of the hull, instead of blowing up the deck and topsides!

These great rents appear rather to have been made by a rock than by the explosion of a powder-magazine."

"There is not a rock in the channel!" answered the sailor. "I will admit anything you like, except the rock."

"Let us try to penetrate into the interior of the brig," said the engineer; "perhaps we shall then know what to think of the cause of her destruction."

This was the best thing to be done, and it was agreed, besides, to take an inventory of all the treasures on board, and to arrange for their preservation.

Access to the interior of the brig was now easy. The tide was still going down, and the deck was practicable. The ballast, composed of heavy ma.s.ses of iron, had broken through in several places. The noise of the sea could be heard as it rushed out at the holes in the hull.

Cyrus Harding and his companions, hatchets in hand, advanced along the shattered deck. Cases of all sorts enc.u.mbered it, and, as they had been but a very short time in the water, their contents were perhaps uninjured.

They then busied themselves in placing all this cargo in safety. The water would not return for several hours, and these hours must be employed in the most profitable way. Ayrton and Pencroft had, at the entrance made in the hull, discovered tackle, which would serve to hoist up the barrels and chests. The boat received them and transported them to the sh.o.r.e. They took the articles as they came, intending to sort them afterwards.

At any rate, the settlers saw at once, with extreme satisfaction, that the brig possessed a very varied cargo--an a.s.sortment of all sorts of articles, utensils, manufactured goods, and tools--such as the ships which make the great coasting-trade of Polynesia are usually laden with.

It was probable that they would find a little of everything, and they agreed that it was exactly what was necessary for the colony of Lincoln Island.

However--and Cyrus Harding observed it in silent astonishment--not only, as has been said, had the hull of the brig enormously suffered from the shock, whatever it was, that had occasioned the catastrophe, but the interior arrangements had been destroyed, especially towards the bows.

Part.i.tions and staunchions were smashed, as if some tremendous sh.e.l.l had burst in the interior of the brig. The colonists could easily go fore and aft, after having removed the cases as they were extricated. They were not heavy bales, which would have been difficult to remove, but simple packages, of which the stowage, besides, was no longer recognisable.

The colonists then reached the stern of the brig--the part formerly surmounted by the p.o.o.p. It was there that, following Ayrton's directions, they must look for the powder-magazine. Cyrus Harding thought that it had not exploded; that it was possible some barrels might be saved, and that the powder, which is usually enclosed in metal coverings, might not have suffered from contact with the water.

This, in fact, was just what had happened. They extricated from amongst a large number of shot twenty barrels, the insides of which were lined with copper. Pencroft was convinced by the evidence of his own eyes that the destruction of the _Speedy_ could not be attributed to an explosion. That part of the hull in which the magazine was situated was, moreover, that which had suffered least.

"It may be so," said the obstinate sailor; "but as to a rock, there is not one in the channel!"

"Then, how did it happen?" asked Herbert.

"I don't know," answered Pencroft, "Captain Harding doesn't know, and n.o.body knows or ever will know!"

Several hours had pa.s.sed during these researches, and the tide began to flow. Work must be suspended for the present. There was no fear of the brig being carried away by the sea, for she was already fixed as firmly as if moored by her anchors.

They could therefore, without inconvenience, wait until the next day to resume operations; but, as to the vessel herself, she was doomed, and it would be best to hasten to save the remains of her hull, as she would not be long in disappearing in the quicksands of the channel.

It was now five o'clock in the evening. It had been a hard day's work for the men. They ate with good appet.i.te, and, notwithstanding their fatigue, they could not resist, after dinner, their desire of inspecting the cases which composed the cargo of the _Speedy_.

Most of them contained clothes, which, as may be believed, were well received. There were enough to clothe a whole colony--linen for every one's use, shoes for every one's feet.

"We are too rich!" exclaimed Pencroft. "But what are we going to do with all this?"

And every moment burst forth the hurrahs of the delighted sailor when he caught sight of the barrels of gunpowder, fire-arms and side-arms, b.a.l.l.s of cotton, implements of husbandry, carpenter's, joiner's, and blacksmith's tools, and boxes of all kinds of seeds, not in the least injured by their short sojourn in the water. Ah, two years before, how these things would have been prized! And now, even although the industrious colonists had provided themselves with tools, these treasures would find their use.

There was no want of s.p.a.ce in the store-rooms of Granite House, but that daytime would not allow them to stow away the whole. It would not do also to forget that the six survivors of the _Speedy's_ crew had landed on the island, for they were in all probability scoundrels of the deepest dye, and it was necessary that the colonists should be on their guard against them. Although the bridges over the Mercy were raised, the convicts would not be stopped by a river or a stream, and, rendered desperate, these wretches would be capable of anything.

They would see later what plan it would be best to follow; but in the meantime it was necessary to mount guard over cases and packages heaped up near the Chimneys, and thus the settlers employed themselves in turn during the night.

The morning came, however, without the convicts having attempted any attack. Master Jup and Top, on guard at the foot of Granite House, would have quickly given the alarm. The three following days--the 19th, 20th, and 21st of October--were employed in saving everything of value, or of any use whatever, either from the cargo or rigging of the brig.

At low tide they overhauled the hold--at high tide they stowed away the rescued articles. A great part of the copper sheathing had been torn from the hull, which every day sank lower. But before the sand had swallowed the heavy things which had fallen through the bottom, Ayrton and Pencroft, diving to the bed of the channel, recovered the chains and anchors of the brig, the iron of her ballast, and even four guns, which, floated by means of empty casks, were brought to sh.o.r.e.

It may be seen that the a.r.s.enal of the colony had gained by the wreck, as well as the store-rooms of Granite House. Pencroft, always enthusiastic in his projects, already spoke of constructing a battery to command the channel and the mouth of the river. With four guns, he engaged to prevent any fleet, "however powerful it might be," from venturing into the waters of Lincoln Island!

In the meantime, when nothing remained of the brig but a useless hulk, bad weather came on, which soon finished her. Cyrus Harding had intended to blow her up, so as to collect the remains on the sh.o.r.e, but a strong gale from the north-east and a heavy sea compelled him to economise his powder.

In fact, on the night of the 23rd, the hull entirely broke up, and some of the wreck was cast up on the beach.

As to the papers on board, it is useless to say that, although he carefully searched the lockers of the p.o.o.p, Harding did not discover any trace of them. The pirates had evidently destroyed everything that concerned either the captain or the owners of the _Speedy_, and, as the name of her port was not painted on her counter, there was nothing which would tell them her nationality. However, by the shape of her boats Ayrton and Pencroft believed that the brig was of English build.

A week after the catastrophe--or, rather, after the fortunate, though inexplicable, event to which the colony owed its preservation--nothing more could be seen of the vessel, even at low tide. The wreck had disappeared, and Granite House was enriched by nearly all it had contained.

However, the mystery which enveloped its strange destruction would doubtless never have been cleared away if, on the 30th of November, Neb, strolling on the beach, had not found a piece of a thick iron cylinder, bearing traces of explosion. The edges of this cylinder were twisted and broken, as if they had been subjected to the action of some explosive substance.

Neb brought this piece of metal to his master, who was then occupied with his companions in the workshop of the Chimneys.

Cyrus Harding examined the cylinder attentively, then, turning to Pencroft--

"You persist, my friend," said he, "in maintaining that the _Speedy_ was not lost in consequence of a collision?"

"Yes, captain," answered the sailor. "You know as well as I do that there are no rocks in the channel."

"But suppose she had run against this piece of iron?" said the engineer, showing the broken cylinder.

"What, that bit of pipe!" exclaimed Pencroft in a tone of perfect incredulity.

"My friends," resumed Harding, "you remember that before she foundered the brig rose on the summit of a regular water-spout?"

"Yes, captain," replied Herbert.

"Well, would you like to know what occasioned that water-spout? It was this," said the engineer, holding up the broken tube.

"That?" returned Pencroft.

"Yes! This cylinder is all that remains of a torpedo!"

"A torpedo!" exclaimed the engineer's companions.
